Title: Shadow mask
Inventor: HIGASHINAKAGAHA EMIKO
IPC: C22C45/02
Filed: 1983-03-09
Abstract: PURPOSE:To enable formation of fine holes with high precision and high density in a shadow mask for electron beams to pass througn, by using an amorphous alloy as the material of the shadow mask. CONSTITUTION:An amorphous alloy is used as the material for a shadow mask, in which the holes for electron beams to pass through are formed by etching. Since the material of the shadow mask is of an amorphous alloy having no crystalline structure, the etched directions on the microscopic structures are completely at random. As a result, the etching direction is macroscopically uniform and the hole for the electron beam to pass through is formed perpendicularly to the etching surface. Thus, a shadow mask can be provided with fine holes having precision and high density for electron beams to pass therethrough.

Title: Static type memory circuit
Inventor: KURAFUJI SETSUO
IPC: G11C11/417
Filed: 1980-03-26
Abstract: PURPOSE: To save current consumption without decreasing a read-out speed by setting the ground-side potential of a memory cell connected to an unselected column line, higher than that of a memory cell connected to a selected column line.  
     CONSTITUTION: When cell MC is half-selected, column address Y is unselected, so transistors QB 12  and QB 13  are turned off. A rise in potential of word line W 1  turns on transistors QB 3  and QB 4  and if transistor QB 5  is turned on, load current ILB flows, but since the potential of common source E 1  of half-selected cell MC rises up to reference potential V ref  owing to dummy cell DC, the value of load current ILB flowing through transistor QB 5  becomes less than that when cell MC is selected. As reference voltage V ref  is raised, load current ILB decreases, but it should be set within the range where the flip-flop of the cell can operate.

Title: Vacuum pump
Inventor: KAWASUE SHIGEO
IPC: F04C18/344
Filed: 1984-02-29
Abstract: PURPOSE:To reduce the generation of noise by installing an exhaust valve mechanism on a moving element side and forming an exhaust passage on the moving element and a moving shaft connected to the moving element and utilizing the synergetic effect of the noise shielding effect by a stator and the noise arresting effect in the exhaust passage. CONSTITUTION:Since an exhaust valve mechanism is installed onto a rotor 4 inside a stator 3, even if noise is generated, accompanied by the opening and closing operation of the exhaust valve (check valve), the stator 3 cuts-off the propagation of the noise outside, and the very high cutting-off effect can be developed. Further, since the exhaust supplied from the internal space 7 in each stator 3 is discharged, passing through the long exhaust passages 9b-9e in maze form which are formed on the rotor 4 and the rotary shaft 4' connected to the rotor 4, the exhaust passages serve as a muffler, and noise arresting effect can be developed. Therefore, by the synergetic effect, the generation of noise in operation can be reduced.
